Shifting issues due to internal problems in high mileage automatic transmissions can be difficult to resolve without transmission replacement.
Rear door drivers-side. When using Keyless entry doors won't lock. The door above is culprit. All others lock. A short alarm sounds when all doors are locked. Presently no alarm sounds. Any suggestions for a fix. By the way I did use my second clicker which is brand new. Therefore battery is new.

2012 Volkswagen Jetta TDI Recalls
On the 2.0L TDI common rail Diesel engine/clean Diesel engine, fuel injection pulses could coincide with the natural frequency of injector line #2. This resonance creates additional stress on the fuel line. Small cracks could develop in the #2 injector line, resulting in a Diesel fuel leak. A fuel leak always increases the risk of a fire. Dealers will install an improved #2 fuel injector line and install vibration dampers on all of the injector lines to correct this concern. The Volkswagen/Audi recall number is 23J9/V5.
